OK, in the history of fighter aircraft, there was always a push to arm these planes with better and more powerful armaments. Throughout history, there were many failed attempts at this, but one such plan stands out as the single most persistent bad idea that I could find. In the race to keep up with certain other countries, one nation developed a gun system that had serious power. the design was actually not originally for aircraft, but rather for use on ships. It was significantly altered for use on a particular aircraft in the 1970s, and it proved to be far more dangerous to the aircraft that carried it than it ever was to any enemy. Results ranged from pilots unable to lower the landing gear, to various electrical systems breaking when the gun was fired, to even loss of the plane itself. One incident was stranger than most--when the pilot fired the gun, the vibrations damaged electrical systems....one of which was the canopy locking system, and the canopy blew clean off the plane in flight.
Name the plane and the gun system.
